Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reception devices for ceramic heating elements are complex and expensive to manufacture due to the need for multiple components and intricate assembly processes.
Innovation Solution
A device with a frictional connection between the contact plate and frame, where the contact plate is made from an electrically conducting material and the frame from an insulating material, allowing for a permanent and simple assembly process, and an insulating layer applied to the contact plate side remote from the heating elements for additional support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the contact plate is positively fixed in the frame by a frame stud, then the connection between contact plate and frame is secure, but the manufacturing process becomes complicated and expensive requiring multiple components and individual assembly steps
Solution Approach 1:
The patent merges the contact plate and frame into a single integrated component where the contact plate is formed as an integral part of the frame structure. This eliminates the need for separate fixing studs and multiple assembly steps, reducing manufacturing complexity while maintaining the secure connection through the unified structural design
Solution Approach 2:
The frame structure is designed to serve multiple functions simultaneously: it provides structural support, electrical insulation, and integrated contact plate formation. The frame studs are repurposed as both structural elements and contact plate positioning features, reducing the need for separate dedicated fixing components
2Adaptability or versatility
If multiple components are used for the reception device, then the functional requirements are met, but the handling and manipulation during manufacture becomes more difficult
Solution Approach 1:
By combining multiple functional components (frame, contact plate, and fixing elements) into a single integrated reception device, the patent reduces the number of separate parts that need to be handled during manufacturing. The integrated design maintains all necessary functional capabilities while simplifying handling and assembly operations
Solution Approach 2:
The reception device is designed with modular functional zones within a single component structure, allowing different functional areas (contact areas, insulating areas, structural support areas) to be clearly defined within the unified piece, making it easier to handle while maintaining functional versatility
